Hagia Sophia is overwhelming on your own – the sheer size, the mix of Christian mosaics and Islamic calligraphy, the stories behind every corner. This official group tour pairs you with a licensed guide who brings it all to life, explaining the building’s wild journey from cathedral to mosque to museum and back to mosque again, pointing out details most people walk right past. You meet the guide outside, pay the entrance fee in cash on the spot (tickets not included), then head in together skipping the confusion of going solo. The group stays manageable so you can hear everything and ask questions. Straightforward way to understand one of the world’s most incredible places instead of just staring up in silence.
